Today, medical professionals have a choice of cadavers, animal, traditional, or virtual reality models, which all have significant limitations. Unlike animal models that only approximate human anatomy and may raise ethical concerns, or cadaver models that cannot retain live-tissue feel and require a controlled environment, Stratasys’ Digital Anatomy 3D Printer recreates actual tissue response – and can be used anywhere without specialised facilities. It also lets users focus on specific pathologies.

The new J750 Digital Anatomy 3D Printer is designed to replicate the feel, responsiveness, and biomechanics of human anatomy in medical models – the system improves surgical preparedness and training while helping bring new medical devices to market faster.

‘We believe in the potential of 3D printing to provide better health care, and the Digital Anatomy 3D Printer is a major step forward,’ said Stratasys healthcare business unit head Eyal Miller. ‘We’re giving surgeons a more realistic training environment in no-risk settings. We also anticipate this will enable medical device makers to improve how they bring products to market by performing design verification, validation, usability studies and failure analysis with these new models.’

The new 3D printer has already been tested at several organisations. The Jacobs Institute, a medical innovation centre focused on accelerating device development in vascular medicine, has been testing the Digital Anatomy 3D Printer to re-create key vascular components for advanced testing and training. ‘3D printing has been wonderful for recreating patient-specific anatomy compared to cadavers or animal models; however, the final frontier for organ model realism has been live-tissue feel and biomechanical realism,’ said Dr. Adnan Siddiqui, chief medical officer, Jacobs Institute. ‘That’s exactly what the Digital Anatomy 3D Printer gives us. We believe these models give us the best opportunity to recreate human physiological conditions to simulate actual clinical situations and to study new devices to establish their effectiveness before introducing them to patients.’

In conjunction with the 3D printer itself, Stratasys is also introducing three new materials – TissueMatrix, GelMatrix, and BoneMatrix – used to create cardiac, vascular, and orthopedic 3D printing applications. A Blood Vessel Cleaning Station that removes support material from inside 3D-printed blood vessels is also being released.
